Which ORY and LT's??
 

I'm purchasing an ORY and LT's and I was wondering which the best brand is. Can you guys help? Price isn't a problem. If I were to get this do I have to get a tune? Will I be able to use the predator programmer?

$$$$- QTP or KOOKs -> the best.
In theory, yes, your Predator can help you tune for the setup.

iF YOUR ON A BUGET JUST GET THE ARMOR COATED PACESETTER LT'S & ORY. BEST BANG FOR THE BUCK. GIVEN THEY ARE NOT STAINLESS BUT YOU WONT SPEND $800 EITHER. YOU CAN GET THEM FOR UNDER $400 FOR THE LT'S & ORY SHOULDNT BE TOO EXPANSIVE. THEN SPEND THE REST ON OTHER MODS.

kooks/qtp's = best
pacesetter = cheapest and still good

correction- pacesetter = cheapest and all you really need, you'll have basiclly the same performance gain for 1/2 the price, but get coated :)

pacesetter or hooker.. if you want cheap and good

Kooks if you want the best..

I always want brand new parts and the best brand...might sound dumb, but that's just me...So when I get these parts I won't have to have em tuned at a shop? I can just use the predator to tune it by myself right??

If you get the pacesetters instead of kooks you would have enough money left to get a P&P TB & underdrive pully. Just food for thought.

QTP's High Velocity Merge Collector LT's bitchslap Pacessetters in terms of performance.

if i was you i would rather get a tune from a shop or with hp tuners. predator does a decent job but the others are a lot better.

dont get hookers and if you care to look into more info on this search, this question is asked 10 times a day

so what ORY should I go with??? If I just had a ORY only will my car be louder than what it is now?

yes it would be louder and you have to get the ypipe made to fit the headers

Most Y-pipes available mash the left and rght pulses together into the I-pipe.
Flowmaster makes the quality Scavenger Merge collector which works incredibly and provides optimal flow.

QTP and Mufflex Y-pipes come with that merge collector, but fitment issues do come up with these Y-pipes, as they come in pieces, have several joints, and are somewhat difficult to install. Most guys bolt-em up, fight with the Y-pipe, lose the battle and drive around with less than stellar ground clearance, therefore, these Y-pipes aren't very popular, despite their superior flow characteristics. I installed mine, then took it to an exhaust shop for final adjustment, and was happy with my QTP ORY. It also flowed incredibly!!!!
Another option is to purchase the merge collector alone and have an exhaust shop custom fab you a Y-pipe.
